In order for the northern parts of the country to get more daylight to work in when they get home from work -we monkey around with the clocks so that they get to go to work earlier...and work in the dark then.
I guess it depends on what you do. Kids get more play time, farmers just keep doing what they always did because you can not get another hour of daylight out of the day no matter how you rearrange the time.
grumble, grumble...
